problem with TCP/IP internetworking feature

[Samson Abramsky]

I have been having problems getting started with this feature. I am
running gawk version 3.1.3 (which runs fine except for this feature -
including the coprocessing).

I have not succeeded in running the first example script as given on page
12 of `TCP/IP Internetowrking with gawk'.
I have verified that `localhost' is present in /etc/hostsa, and that
`daytime' is present in /etc/services.
I also tried numerous variations, using  local machine domain names,
IP addresses, etc.
This was both on a system running GNU/Linux, and on one running SunOS.

Here is the script (which was taken from the manual as mentioned).


BEGIN {
"/inet/tcp/0/localhost/daytime" |& getline
print $0
close("/inet/tcp/0/localhost/daytime")
}

The error message I get is:

>gawk; foo:2 fatal: can't open two way socket
'/inet/tcp/0/localhost/daytime' for input/output (No such file or
directory).

(having run: gawk -f foo)

I realize that this is most likely an configuration issue, but the inet
package
is part of the gawk implementation, and I have followed all the
instructions carefully, so it is quite frustrating that it doesn't work.

Any help you can provide would be much appreciated!

Best wishes,
